目前RFID技术在各个领域中广泛应用，且还未形成统一的全球化标准，市场为多种标准并存的局面，由于各个标准中对于调制方式的定义不同，给不同标准间的通信和检测带来了较大的障碍。因此，正确地识别出RFID调制方式是实现通信互联和信号测试等处理的前提，RFID调制识别的研究逐渐成为国内外RFID测试中的研究热点。提出一种新的基于瞬时信息的调制识别方法，该方法是以RFID调制信号的瞬时信息为基础，提出了两个新的特征参数Ra和Rf，设计了调制识别分类器进行有效识别。仿真结果表明，该方法的复杂度降低，且RFID调制信号的识别正确率有了很大程度的提高。

Currently,RFID technology is widely used in various fields. However,there isn’t a unified global standard and multiple standards coexist. Because the definition of modulation modes in various standards is not identical,it is difficult for the detection and the communication between diferent standards. Therefore,the correct identification of RFID modulation modes is the precondition for communication interconnection and signal processing,and the RFID modulation recognition has become a re-search hotspot in RFID testing area at home and abroad. A new RFID modulation recognition method based on instantaneous in-formation is proposed in this paper,in which two new parameters(Ra and Rf)are presented on the basis of RFID modulation sig-nal instantaneous information. A classifier of for modulation recognition was designed for effective recognition. The simulation re-sults show that the complexity is significantly reduced by the method and the correct recognition rate of RFID modulation signal is improved to a great extent.
